CLOSURE FOR COLLAPSIBLE TUBES AND THE LIKE Filed April 29, 1929 Patented Oct. 14, 1930 UNITED STATES WALTER T. DAVIS, OF WHEELING, WEST VI PATENT OFFICE RGIIN'IA, ASSIGNOR TO WHEELING STAMP- ING COMPANY, OF WHEELING, WEST VIRGINIA, A CORPORATION OF WEST VIR- GIN IA CLOSURE FOR COLLAPSIBLE TUBES AND THE LIKE Application filed-April 29,

secured to the container, so that itcannot become lost or misplaced.

The invention may be readily understood by reference to the accompanying drawing, in which Figure 1 is a side elevation of a collapsible tube having my invention applied thereto;

Figure 2 is a transverse vertical section on the plane of line 11-11 of Figure 1 and Figure 3 is a view in elevation similar to Figure 2, showing the closure in its inoperative position. i p

In the drawings. 2 designates a suitable container, preferably acollapsible tube,.having a neck portion 3 with a discharge passage 4 therethrough. -Formed in the top of the neck is a transverse rounded groove 5.

Secured to the tube at each side ofthe neck is a bail 6 of a resilient construction, the ends of the bail being secured to lugs or ears 7. I prefer that the bail. be'in the form of a small spiral spring. Carried on this bail, and rotatable thereon, is a roller 8 which is adapted to rest in the transverse groove 5 and which has a curvature conforming substantially to the curvature of the groove. 1

l-Vhen the roller is resting in the groove,

i. the bail or spring 6 is under tension, and

serves to hold-the roller tightly in the groove, the roller thereby, serving to'close the dis-' charge opening in the tube. i To move the closure to inoperative position, it is merely necessary to press upon it with suflicient force to slip or roll it out of the groove-,5. The spring 6 will then act to pull the roller to one side of the neck of the tube,

where it will not interfere with the discharge of the contents of the tube. To close the tube,

,more convenient to use than ferred embodiment compositions.

the roller is merely pushed back into place against the tension of the spring bail 6. It will be noted that the top of the tube on each side of the groove 5 is preferably sloped outwardly in order to facilitate the movement of the roller into and out of operative position; The closure is of such a nature that the tube can be held in one hand and the closure moved into and out of operative position by the use of the thumb.

Being permanently attached to the tube, the closure cannot become lost or misplaced. Inasmuch as it can be easily moved into and out of operative position with one hand, it is the ordinary screw cap heretofore provided. The device can be cheaply made and can be easily ap- I plied'to the tubes in the manufacture thereof.

lVhile I have shown and described a preof my invention, it will be understood that otherwise embodied, and that the closure-may be applied to other to receptacles adapted to receive semi-solid or semi-liquid I claim as my invention: I i

1,. The combination with a receptacle having a neck portion with a discharge passage therethrough and a transverse groove across the top of the neck, of a closure comprising a roller adapted to normally rest inthe. groove and movable out of the groove to permit discharge of the contents: of the receptacle, and a spring bail for yieldably retain-- ing theroller in place. 4

2. A a discharge passage therethrough and a transverse tlOfi, a resilient bail anchored at each side of the neck portion, and a roller carried on the invention may be receptacles than collapsi- 'ble tubes, and particularly receptacle having a neck portion with groove in the end of the neck porsaid bail adapted to be received in the groove groove, a roller adapted to normally be received in the groove, and a resilient bail on which the roller is carried.

4. A collapsible tube having a neck portion with a discharge orifice therein, and a transverse groove inthe end of the neck portion, the end of the neck at each side of the groove being sloped outwardly away from the groove, a roller adapted to normally be re ceived in the groove, and a resilient bail passing through the roller and being secured to the tube at each side of the neck, said resilient bail being in the form of a helical metal spring.

In testimony whereof Ihave hereunto set my hand.
